Probiotic-strain fermentation lysate. Common K-beauty 'microbiome-friendly' ingredient.
What it does
Lactobacillus ferment lysate is the cellular debris and metabolites left after fermenting a Lactobacillus strain. Topical use is positioned around 'microbiome support' — the realistic effect is mild surface-soothing and humectant activity rather than a meaningful change to the skin's microbiome. Common in K-beauty essences and 'glass skin' positioning.

Adding more steps does not equal more efficacy.Draelos 2018 · Journal of Cosmetic Dermatology ↗
